Adjacent to the ,vdrivers seat arefulcrumed hand levers 33 and 34 one of which 1s connected to one of thebell-cranks, and the other to the other bell-crank by a rod 85 or othersuitable connection. The levers 33 and 34: are provided with the usualtoothed segments and spring vIn case of deep snows, where the spurs 18Icannot start the sleigh, an auxiliary propelling mechanism is employed.This mechanism comprises a pair of levers 86 each loosely inoivinted atone end on a crank 37 on the The levers are of suoli a length that whentheir free ends are released, they extend at an inclination to theground, the

free ends being engageable therewith. lVith the levers in this position,when the shaft 10 `is turning, said levers operate to push, the sleigh.forwardly. l/Vhen not in use they may be elevated and held in suchposition by f means of a catcliBS carried bythe sleigl'il.

On the cranks 37 is also mounted a 'second pair of levers 39 operatingin the same'manner as the levers 3 6, but extending 1n an oppositedirection so that when they are swung downwardly into operativeposition, the sleigh will be backed. To the hind l i sleigh body arefastened leaf springs 40 having at their free ends slots 41 throughwhich the levers 36 and 89 loosely pass, and whereby they are guided.The springs have suflicient flexibility to permit'the levers to beelevated and placed in the catches 38'.
